What this measures

The price level index (PLI) is the ratio of a purchasing power parity (PPP) conversion factor to the corresponding market exchange rate between two countries, expressed relative to a base country that is set equal to 100. For this series the base country is the United States. It provides a measure of the differences in price level between the country and the United States by indicating the number of units of the common currency (US dollars) needed to buy the same volume of the aggregation level in each country. This indicator provides a measure of the differences in the price levels of countries at the level of Households and NPISHs final consumption expenditure.

Limitations: Global PPP estimates underlying this indicator are produced by the ICP Global Office and regional implementing agencies, based on data supplied by the national implementing agencies in the participating economies, and in accordance with the methodology recommended by the ICP Technical Advisory Group and approved by the ICP Governing Board. As such, these results are not produced by participating economies as part of their national official statistics. Price level index are not recommended to use as a precise measure to establish strict rankings of countries.

Regional and income-group figures are computed by the World Bank as a no aggregation provided for this indicator in wdi..
